35150 SPIND_DES_VELO_TOL
- Spindle speed tolerance
-
- -
Description: In spindle control mode, the set speed (programmed speed x spindle offset,
allowing for limits) is compared with the actual speed.

MD irrelevant to:

•
Example:
MD 35150 $MA_SPIND_DES_VELO_TOL = 0.1
The actual spindle speed must not deviate from the set speed by more than +/
- 10%.

MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START
(feed enable for spindle in setpoint range)
MD35100 $MA_SPIND_VELO_LIMIT
(maximum spindle speed)
NC/PLC interface signal DB390x DBX2001.5 (Spindle in setpoint range)
NC/PLC interface signal DB390x DBX2001.0 (Speed limit exceeded)

Description: A limiting value for the maximum spindle speed is entered in MD35160
$MA_SPIND_EXTERN_VELO_LIMIT, which is taken into account exactly when the NC/
PLC interface signal DB380x DBX3.6 (Velocity/speed limitation) is set.
The control limits a spindle speed which is too high to this value.

If the actual speed deviates from the set speed by more than MD35150
$MA_SPIND_DES_VELO_TOL, the NC/PLC interface signal is DB390x DBX2001.5
(Spindle in setpoint range) is set to zero.
If the actual speed deviates from the set speed by more than MD35150
$MA_SPIND_DES_VELO_TOL, the path feed is disabled (positioning axes con-
tinue traversing).
If the actual speed exceeds the maximum spindle speed (MD35100
$MA_SPIND_VELO_LIMIT) by more than MD35150 $MA_SPIND_DES_VELO_TOL, the
NC/PLC interface signal is DB390x DBX2001.0 (Speed limit exceeded) is
enabled and alarm 22050 "Maximum speed reached" is output. All axes and
spindles on the channel are decelerated.
